The front man lost his footing at the festival in Gothenburg, Sweden, and went flying off the edge of the stage onto the floor below.

While he managed to carry on performing as paramedics patched him up,band have had to cancel their tour while he recovers.

"The funniest thing happened to me the other day in Sweden," Dave says, in an open letter published on the Foo Fighters' site.

"As I lay there on my back, I just thought, “Are you kidding me? We haven’t even gotten to the screamy bit of the song and the gig is f***ing OVER?” So, I asked for a microphone and told the audience I’d get fixed up and come right back to finish the show ASAP. Shock? Probably. But, I couldn’t stand the thought of such a perfect night going to waste!

He goes on: "All in all, it was without a doubt the single most bizarre Foo Fighters show in the entire 20 years of being a band.

"So….here I am, recovering with 6 metal screws in my leg, thinking about a lifetime of holding up TSA lines from here to Kalamazoo….damn.

"Here’s the not so witty bit…….My doctors have advised me to lay low for a while. The most important thing now is for me to recover from the surgery, to keep my leg elevated so as to keep swelling down and prevent any infection/complication that could do long term damage. I’m not out of the woods yet, folks…

"Which means, and it kills me to say it…..the doctors have told us to cancel shows. I’m really so sorry, guys. You know I hate to do it, but I’m afraid it’s just not physically possible for me at the moment. We’re doing our best right now to work out a plan, so bear with us. You know we’re good for our word. But for now, I need to make sure we have YEARS of gigs ahead of us….

"You have always stood by our band, and we will always stand by you. Like I say at every show, we wouldn’t be here if it weren’t for you guys. And I mean that. I thank you from the bottom of my heart. And I will do everything I can to come back and give you a night to remember for the rest of your lives AS SOON AS POSSIBLE."

A statement on the band's website read: "Due to injuries sustained in Dave Grohl’s fall from the stage during Foo Fighters’ June 12 show at Ullevi Stadium in Gothenburg, Sweden, doctors have required the cancellation of the remainder of the band’s dates in the UK and Europe.

"After undergoing surgery Monday, Dave’s full recuperation time is still to be determined.

"It was previously announced that Foo Fighters’ June 14 appearance at the Pinkpop Festival and June 16 show at the AFG Arena in St. Gallen, Switzerland were cancelled. The following dates have now been cancelled as well: June 19 & 20 - London, UK - Wembley Stadium, June 23 - Edinburgh, UK - BT Murrayfield Stadium, June 25 - Werchter, Belgium - Festivalpark Werchter, June 26 - Glastonbury Festival 2015"

The dramatic video of the incident showed Grohl go flying off the stage and into the crowd.

As the star is tended to by a paramedic on the floor, he appears to still be in high spirits and tells the crowd: "I think I just broke my leg. I think I really broke my leg.

"You have my promise right now that the Foo Fighters we're going to come back and finish this show, but right now I'm going to go to hospital and I'm going to fix my leg and then I'm going to come back and we're going to play for you again."

As the crowd cheered, he continued: "I'm so sorry. I'm so sorry. But right now Taylor Hawkins, you've got to do it."

Fans took to social media to praise the former Nirvana drummer who left the stage to be treated backstage.

While Grohl was attended to backstage, the rest of Foo Fighters played a set of covers sung by drummer Hawkins.

15 minutes later Grohl the front man then returned to the stage with his leg wrapped and finished the concert sitting in a chair.

“I may not be able to walk or run but I can still play guitar and scream,” he said.

The star continued to rock out on stage, and shared a photo of his X-ray on the band's official Twitter page.
